[0043] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the accompanying drawings.

[0044] Please refer to Figures 1 to 10 a specific embodiment of a valve core disassembly tool shown. This special valve core disassembly tool can easily remove the faulty valve core without the need to replace tool heads of different sizes multiple times during the disassembly and assembly process, solving the problem that the existing disassembly tools are mainly scattered manual tools and need to replace tool heads of different sizes during the disassembly process. When encountering a rusty valve core, it is difficult to disassemble, time-consuming and laborious.

[0045] As Figures 1 to 10As shown, in this embodiment, the special valve core disassembly tool includes a tool body 1 and a hexagonal wrench 2 with a conical extractor 21. The tool body 1 is detachably connected to the hexagonal wrench 2. The tool body 1 includes a square opening part 11, a hexagonal part 12, an internal hexagonal through hole 13, and a clamping part 14. A number of square opening parts 11 and hexagonal parts 12 of different specifications are arranged along the axial direction of the tool body 1. The internal hexagonal through hole 13 penetrates the tool body 1 radially. The clamping part 14 is arranged radially inside the tool body 1 and moves horizontally along the internal hexagonal through hole 13. The hexagonal wrench 2 extends into the internal hexagonal through hole 13 and engages with the clamping part 14, enabling combinations in various forms and achieving different functions.

[0046] Specifically, as Figures 5 to 8 shown, the clamping part 14 includes a sliding slot hole 141, a release pin 142, a sealing set screw 143, and an elastic member 144. The sliding slot hole 141 is horizontally opened inside the tool body 1 and is connected to the internal hexagonal through hole 13. The release pin 142 slides along the sliding slot hole 141, and one side of the release pin 142 extends into the sliding slot hole 141 and engages with the hexagonal wrench 2. The sealing set screw 143 is arranged at one end of the sliding slot hole 141. The elastic member 144 is arranged between the release pin 142 and the sealing set screw 143 and abuts against the release pin 142 and the sealing set screw 143 respectively. Preferably, the elastic member 144 is a spring. During use, the release pin 142 is pressed, and the release pin 142 slides to the bottom along the sliding slot hole 141. The release pin 142 compresses the spring, and the hexagonal wrench 2 is inserted into the internal hexagonal through hole 13. The release pin 142 is released, and the release pin 142 engages and fixes with the hexagonal wrench 2 through the thrust of the spring.

[0047] Furthermore, one end of the release pin 142 extends out of the sliding slot hole 141. A convex block 1421 is provided on the release pin 142. The convex block 1421 slides along the inner wall of the sliding slot hole 141 and abuts against the outlet of the sliding slot hole 141 for limiting the release pin 142. The release pin 142 can slide in the sliding slot hole 141 and is limited in the sliding slot hole 141 by the convex block 1421.

[0048] Furthermore, a clamping block 1422 is provided at the bottom of the release pin 142. A groove 1423 for placing the elastic member 144 is recessed at the bottom of the clamping block 1422. One side of the clamping block 1422 extends into the sliding slot hole 141 and is engaged with the hexagon wrench 2. A circular clamping block 1422 is provided at the bottom of the release pin 142. The clamping block 1422 abuts against the inner wall, and one side of the clamping block 1422 extends to the connection between the sliding slot hole 141 and the internal hexagon through hole 13. When the release pin 142 is pressed, the clamping block 1422 slides to the bottom of the sliding slot hole 141. The hexagon wrench 2 is inserted into the internal hexagon through hole 13. The release pin 142 is released, and an elastic force is applied to the release pin 142 by the spring to reset the release pin 142. The part of the clamping block 1422 extending into the internal hexagon through hole 13 slides and is engaged with the hexagon wrench 2 to fix the hexagon wrench 2 in the internal hexagon through hole 13.

A second square opening part 112 is connected to the bottom of the first sleeve part 113. A first connection hole 114 is radially opened in the first sleeve part 113. The hexagonal handle 22 extends into the first connection hole 114 to be used as a handle. The size of the first square opening part 111 is set to 8 mm, and the size of the second square opening part 112 is set to 16 mm, so that the corresponding square opening part can be adopted when different sizes are needed. The first sleeve part 113 can be used in combination with a power tool. The first sleeve part 113 is placed into the power tool for driving, and the hexagonal part 12 is used as one end of the disassembly tool to perform the disassembly work.

[0058] Example 5:
